Something that I found to be beneficial was to look at the JAM 220 study guide. (All of the macro material for Exam 2 was taken from the old exam 220.) I familiarized myself with this, and then went back to the study notes for reinforcement.

For the Economics on course #2 (both micro and macro) what you need are intermediate (junior in college) level books. That is what the Price Theory (micro) book is. For Macro you can try Gordon's Macroeconomics, or most any book that you find available in the genre. I like Gordon because it was my introduction to the subject (my major in college) and has lots of graphs.

Whoever said it was right about doing graphs yourself, its just like working out problems in math.
